Featuring true SPDT outputs and a robust 30A rating, it’s a versatile, drop-in replacement relay designed for HID lights, LED bars, fuel pumps, and more. Its polarity-sensitive solid-state timer ensures reliable, chatter-free operation, making it an essential upgrade for professionals seeking durability and performance in power management. ## Description The Aharon Time Delay Relay is a specialized 12V 30A solution designed to solve "hard start" issues, voltage surges, and signal chatter. By introducing a consistent 10-second delay upon receiving power, it ensures your power source stabilizes and the engine finishes cranking before downstream accessories engage.Key Technical Insights:"Delay-On" Logic: The 12V trigger signal (Pin 86) must remain constant for the full 10 seconds before power switches to Pin 87. If power is removed, the timer resets immediately.Size & Fit: This relay is taller than standard automotive relays. Please check your fuse box clearance before installation.Polarity Sensitive: Due to the internal electronic timer, Pin 85 MUST go to Ground and Pin 86 to the 12V Trigger. Swapping them will prevent operation.Wiring Configuration:Pin 30: Constant 12V (Battery)Pin 85: Ground (Negative)Pin 86: 12V Switched TriggerPin 87: Delayed 12V Output (Normally Open)Pin 87a: Immediate 12V Output (Cuts off after 10s delay)Common Applications:Automotive: Protects HID/Xenon systems from startup surges and prevents LED light bars from flickering during engine cranking.Heavy Machinery: Delays high-capacity radiator fans on forklifts during ignition, reducing initial starter motor load.Fluid Management: Eliminates solenoid "chatter" and rapid cycling on Reverse Osmosis (RO) water filters caused by water ripples across float switches.Diesel & Marine: Delays fuel pumps or compressors so glow plugs can warm up without battery drain, and silences marine oil pressure alarms during startup. Review: Reliable relay for a good price. - I bought this relay to switch on an external hard drive 10 seconds after the computer is turned on. It’s easy to wire up, the connectors are firmly in place and the price was very reasonable. Review: Drop in replacement for LED bar - My LED bar on my F250 truck was having failures in the LEDs. The manufacturer replaced it but the same thing continued to happen. After some investigation it turns out that when the engine is starting the batteries surge causing the LEDs to age. The LED bar is connected to the battery with an automotive relay but it engages as soon as the starter is engaged. Adding this 10 second delay should fix the surge problem. The relay was a drop in replacement for the one that came with the LED bar. ## Features - Automatic 10-Second Delay-On: Prevents high-draw accessories from engaging until the engine has finished cranking. Ideal for protecting sensitive electronics from voltage surges, battery strain, and power fluctuations during startup. - True SPDT Functionality: Features both Normally Open (87) and Normally Closed (87a) pins. Use it to delay a circuit from turning on or to have a circuit turn off automatically after 10 seconds. - Heavy-Duty 30A Rating: Rated for up to 30A switching. Note: For high-continuous loads (over 15-20A) or sensitive applications, it is recommended to use this as a trigger for a secondary high-amp power relay. - Broad Compatibility: A "drop-in" replacement for standard 5-pin automotive relays. Versatile enough for vehicles, heavy machinery, marine equipment, and specialized fluid or electrical systems. - Polarity Sensitive: Unlike standard mechanical relays, this unit contains an internal solid-state timer. Pin 85 must be connected to Ground and Pin 86 to the 12V Trigger for the timer to function. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0744HSF8P | | Best Sellers Rank | #73,540 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Replacement Time Delay Relays | | Brand | Aharon | | Brand Name | Aharon | | Coil Voltage | 12 Volts | | Connector Type | Wired | | Contact Current Rating | 30 Amps | | Contact Material | Silver Or Copper | | Contact Type | Normally Closed, Normally Open | | Current Rating | 30 Amps | | Customer Reviews | 4.1 out of 5 stars 202 Reviews | | Item Weight | 31 Grams | | Manufacturer | Aharon | | Maximum Switching Current | 30 Amps | | Minimum Switching Voltage | 11 Volts | | Model | 60 | | Mounting Type | Socket Mount | | Operating Time | 10 Seconds | | Operation Mode | Automatic | | Part Number | 60 | | Unit Count | 1.0 Count | | Wattage | 420 watts | ## Product Details - **Connector Type:** Wired - **Contact Material:** Silver Or Copper - **Contact Type:** Normally Closed, Normally Open - **Current Rating:** 30 Amps - **Mounting Type:** Socket Mount ## Images ![Aharon 12V 30A Time Delay Relay (10-Second Delay-On) – 5-Pin SPDT Automotive Relay for HID, LED Light Bars, Fuel Pumps, and Accessories - Image 1](https://m.media-amazon.com/images/I/71XWH+LV7gL.jpg) ![Aharon 12V 30A Time Delay Relay (10-Second Delay-On) – 5-Pin SPDT Automotive Relay for HID, LED Light Bars, Fuel Pumps, and Accessories - Image 2](https://m.media-amazon.com/images/I/614lRbVadLL.jpg) ![Aharon 12V 30A Time Delay Relay (10-Second Delay-On) – 5-Pin SPDT Automotive Relay for HID, LED Light Bars, Fuel Pumps, and Accessories - Image 3](https://m.media-amazon.com/images/I/61UYhluZK3L.jpg) ## Questions & Answers **Q: Hey, doe's anyobdy have a datasheet of this product? what is the coil induction and resistance? and another important details** A: Hi , please see all the specs below: Rated Voltage: 12V Operating Voltage: 11VDC ~ 15VDC Delay time (operate time): 10SS ± 2S Contact Rating (resistive): 30A/14VDC Max. Switching power: 420W Shock resistance: 147m/s2 11ms Vibration resistance: 10~40 Hz double amplitude 1.5mm Terminals strength: 100N Ambient Temperature: -40℃ ~ +85℃ Relative Humidity: 85% (at 40℃) Weight (approx.): 40g **Q: Does the output stay on for 10 sec after trigger is removed?** A: No i don't think so. I used this relay to create a 10 second delay on my truck headlights. So the lights turn on 10 seconds after powering the relay. But whenever you remove the trigger power lights go off. **Q: Can this be used to steady a noisy float switch? Is frequent timer cycling bad for it?** A: That's what I'm using it for. Just make sure that the surge isn't what's cycling the pump. I used a 10' length of 1/4" tubing between the pump and switch to dampen the pulse. **Q: Does it come with harness** A: Hi :) No without wire harness, just the relays. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable relay for a good price. *by M***T on December 16, 2025* I bought this relay to switch on an external hard drive 10 seconds after the computer is turned on.
